[pt] Este trabalho apresenta o desenvolvimento de uma ferramenta computacional gráfico-interativa para a verificação de vigas de concreto protendido com pós-tração aderente ao estado limite de serviço, de acordo com a norma brasileira NBR 6118:2014. A ferramenta é uma extensão (addin) para o Autodesk Robot Structural Analysis Professional , que serve como plataforma de modelagem estrutural. A partir de dados fornecidos pelo usuário através de uma interface gráfica, o programa desenvolvido calcula todas as perdas de protensão que ocorrem ao longo da vida-útil da estrutura, assim como os carregamentos equivalentes à protensão durante este período. O trabalho apresenta os métodos de cálculo tradicionais das perdas imediatas e diferidas, obtidos da NBR 6118, e as modificações que tiveram que ser feitas para permitir um cálculo incremental. Exemplos de utilização do programa e dos cálculos necessários também são apresentados e comprovam, pelos bons resultados obtidos, o acerto na escolha da metodologia escolhida. Como resultado, a ferramenta apresenta duas saídas: uma planilha contendo os esforços e as tensões atuantes na viga ao longo de sua vida-útil e verificações destes valores em relação aos limites estabelecidos para o estado limite de serviço; e o modelo estrutural no Robot apresenta os carregamentos equivalentes da protensão. O usuário pode então adotar estes carregamentos em demais cálculos da estrutura, enquanto a planilha pode ser utilizada para verificar com facilidade se a protensão atende às condições de serviço. / [en] This work presents the development of an interactive graphics computational tool for the verification of prestressed concrete beams with posttensioned bonded tendons to the serviceability limit state stress check according to the Brazilian code NBR 6118:2014. The tool is an add-in for Autodesk Robot Structural Analysis Professionalr, which serves as a structural modeling platform. With data supplied by the user through a graphics user interface, the program here developed calculates all relevant prestress losses that occur throughout the structure s life-cycle, along with the prestressing s equivalent loads during this period. The traditional calculation methods, obtained in the NBR 6118, are presented along with the modifications which had to be implemented in order to allow for incremental loss calculations. Usage examples and the necessary calculations are presented and, through the results obtained, validate the adopted methodology. As results, the program presents two outputs: a spreadsheet containing the resultant forces and stresses and a check of these values with respect to the permissible stresses in the serviceability limit state; and the Robot model presents the prestress equivalent loads. The user may then use these loads in additional calculations. The spreadsheet may be used to easily check if the prestress is sufficient with respect to serviceability conditions.

Inom 3D-grafik, visualiseringar, spel och VR finns ett behov av måttriktig modellering. Traditionellt så används CAD-program för att uppnå ett exakt eller precist resultat. Men då CAD-program inte utmatar polygonal geometri så fungerar det inte att använda resultatet direkt i tidigare nämnda kategorier. Denna studie ämnar att underlätta måttriktig polygonal modellering i Autodesk Maya genom ett tillägg i form av ett grafiskt användargränssnitt. Effektiviteten av detta mäts genom tidtagning på modellering av CAD-ritningar i polygoner hos en testgrupp både med och utan tillägget samt en kvalitetskontroll där resultatet jämförs med specifikationen. Medelresultatet av testgruppens användning av tillägget var en förbättring i tidsåtgång gentemot endast Maya. Geometrin hade även bättre måttriktighet.

This diploma thesis focuses on processing and data collecting for the use of creating functional 3D informating model that we call BIM (Building Information Modelling) which is getting more and more attention throughout building industry and it is used by all of the participants in the industry from designers and architects to those who are dealing with building installations. This process is slowly getting into legislations of many countries including Czechia. The thesis is divided into two parts where one of them is describing the Building Information Modeling in general and the other part is describing the work which is behind the colleting good data which is needed when making the 3D documentation in Revit software which is wildly used for designing building constructions. Practical part of the land surveyor´s work is devided here into two parts where one of them is dedicated to collecting data by laser scanning process, GNSS and measuring by total station and levelling machine. Second part focuses on the description of the data processing in order to make 3D model. The example of the output production data is the BIM 3D model of the family house in selected level of detail and besides that we also have the visualization of both interior and exterior and 2D simplified building documentations.

This dissertation about the Stirling engine deals with the history and formation of the heat engine. At the beginning of this work, fundamental parts and their functions are described, elucidating the principle of operation explained by the thermodynamic cycle and subsequently comparing the ideal and the real Stirling cycle and last but not least provides various modifications whilst describing their differences. The mathematical model of the Stirling engine is processed by Schmidth’s theoretical analysis and thereafter is created in PScad v46. The process of creating a model is shown in one of the chapters of this dissertation. The results were taken into account in the design of 3D models in Inventor Professional by Autodesk. The work concludes with the evaluation of the computational model and its functionality as well as the documentation of the 3D model.

Reducing and managing the environmental impacts of building structures has become a priority of building stakeholders and within the architecture, engineering and construction (AEC) community; although, conflicting approaches and methods to combat the issues are present. For example, green building standards are widespread throughout the world; however each one has its own characteristics and consequently its own specific requirements. While all have proven to be effective rating systems and have similar requirements, the distinguishing characteristic that separates them is their treatment of performance and prescriptive metrics. The feature they all severely lack or currently limit is the inclusion of strict engineering evaluation through energy simulations; hence, the reason why they fail to offer procedural steps to meet performance metrics. How can design professionals design energy efficient buildings with such constraints? Fortunately, advances in technology have allowed design professionals access to content found in Building Information Modeling (BIM). However, extracting pertinent information for specific use in energy analysis is problematic because BIM software currently available is filled with interoperability issues when placed in external software for energy analysis and energy analysis software itself is created with many assumptions that affect the tabulated energy results. This research investigates current building rating systems, determines how current professionals meet energy requirements, and prove that it is possible to create an add-on feature to Autodesk Revit that will allow design professionals to extract the needed information to meet energy goals with actual prescribed methods of mechanical systems selection and evaluation.

This thesis is focusing on the use of the finite element method (FEM) in program environment of Autodesk Inventor Professional (AIP) 2010. For the analysis of the components or assemblies with FEM serves the Strength analysis module of the AIP 2010, whose environment and functions are detailed in this thesis. At the conclusion practical examples of modal and static analysis on the synchronous generator rotor model are demonstrated including a brief evaluation of the results.
